Milltek Sport exhaust system for BMW 3 Series F80 M3 / 4 Series F82-F83 M4

Replacing the original system with a Milltek Sport exhaust brings back the character that the engine of your BMW 3 Series F80 M3 / 4 Series F82-F83 M4 is held back from the factory: a rounder tone at idle that opens up cleanly through the revs, without gimmicks.

The questions we get asked most

• Drone on the highway? It's the number one concern on forums. This version keeps a resonator: the sound stays full under acceleration, but the system stays composed at steady cruising speed, ideal for everyday driving.
• What about the neighbors in the morning? The valves are controlled just like the factory system: closed and discreet on startup or in comfort mode, fully open in sport mode.
• Homologation: this system is ECE / EC approved, a real plus for driving with peace of mind and passing the French contrôle technique.
• Installation: fitting requires cutting the factory exhaust. We recommend having a professional handle the installation.
